LUBRICATOR.

SPECIFICATION lforming part of Letters Patent No. 755,802, dated March 2,9,` 1904.

Application led July 2.0, 1903. Serial No. 166,344. (No model.)

.T0 a/ZZ whom it www concern:

Be it known that I, Go'rTLErB SCHNEIDER, a citizen of the United States, residing at Bluffton, in the county of Wells and State of In,- diana, have invented a new and useful Lubricator, of which the following is a specification.

This invention relates to lubricators, and more especially to lubrieators for windmills, in which it is desirable that the lubricator may be so constructed that it may be supported at the top of the windmill-'tower and operated at intervals by a person on the ground at the base of the tower.

The principal object of the invention is to provide in a lubricator fr the purpose specified means for discharging from the reservoir of the lubricator a predetermined quantity of oil and means for distributing'the oil so discharged to the different portions of the windmill-gearing in quantities proportionate to the requirements for oil at the different points to' which it is distributed.

A further object of the invention is to provide in a lubricator of the type specied an improvedv form of measuring discharge-valve by means of which the waste of the oil from feeding excessive quantities to the bearings of the windmill-gearing may be eifectively prevented and which will at `all times be ready for positive and eficient action.

With the objects above mentioned and others in view, which will appearas the invention is more fully disclosed, the same consists in the construction and combination of parts of a lubricator for windmills, as hereinafter described and claimed, and illustrated in the accompanying drawings, in which is illustrated a preferred form of embodiment of the invention capable of carrying the same into practical operation, it being understood, however, that various changes in the form, proportions, and exact mode of assemblage of the elements therein exhibited may be made without departing from the spirity of the invention.

In the drawings, Figure 1 is a view in vertical section through the lubricator. Fig. 2

is a detail View in section through the discharge-valve in a vertical plane at right angles to the plane of section upon which Fig.

1 is taken. Fig. 3 is a detail view showing the stop devices to limit the range of movement of the rotatable valve-plug.

Corresponding parts are designated by the samecharacters of reference throughout.

Referring to the drawings'in detail, l designates the side wall ofthe reservoir of the lubricator, which is preferably of cylindrical form and which may be constructed of any suitable material-such, for example, as galvanized sheet-iron.

2 designates the cover of the reservoir, which is preferably of the form shown and which is adapted, while forming a sufliciently close it within the top of the reservoir, to protect the oiltherein from contamination by foreign matter and to prevent evaporation, to be readl ily removed.

The bottom 3 of the reservoir is of heavier material than the sides and cover and is made with a slight slope toward the center, at which is provided the discharge-opening 4, which is internally threaded for engagement with the threaded upper end 5 of a branch pipe extending up from the measuring discharge-valve 6.

The discharge-valve 6 comprises a tapered seat7 of frusto-conical form, which communicates with the branchv pipe 5 above mentioned by means of an oblong opening 8 and which is provided on the under side with a large round opening communicating with the bore of a downwardly-disposed branch pipe 9. The valve-plug l0 is of frusto-conical form to insure smoothtting within the tapered seat 7 and is formed with an internal cavity 11, 85 which has an inlet-opening 12 and a dischargeopening 13, separated by an interval of ninety degrees, the discharge-opening .being closed when the inlet-opening registers with the oblong opening 8 in the upper part of the valve- 90 i seat and the-inlet-opening being closed when the discharge-opening is over the open end of the lower branch pipe 9. The movement of the plug l0 within the valve-seat 7 is limited by a lug 14 upon the stem of the plug and a pair 95 of lugs l5 and 16, arranged uponl the end of the valve-seat in position to be engaged by the lug 14.. The plug 10 is secured in the seat by means of a washer 17, tted over a reduced extension 18 upon the smaller end of the valve- IOO plug and secured upon the extension to rotate therewith. A nut 19 external to the washer holds it in position upon the extension 18..

Movement is imparted to the valve-plug by means of a lever-arm 20, secured upon the square end of the stem of the plug and provided near one end with an adjustable weight 21, secured in position upon the lever by means of a set-screw and provided at the other end with an opening 22, through which passes a wire 23, which extends from the lubricator downward to a point within reach by a person standing on the ground.

The lower branch pipe 9 is internally thread- `ed for engagement with the threaded upper end of the distributing-pipe 24, which extends downward a suitable distance and is provided at its lower end with a nut 25, having the lower portion thereof rounded and externally threaded, as shown, for the engagement of a distributer 26,the bottom of which is formed into a cone 27, which projects upward within the chamber formed in the distributer and forms means to spread the oil outward toward the wall of the distributing-chamber. Along the line of junction of the bottom of the distributingchamber with the side wall thereof there are formed a plurality of threaded apertures to receive distributer-pipes 28, which distribute the oil from the chamber to the various parts of the windmill-gearing at which the oil is required. These pipes 28 are adjusted in position in the threaded apertures in the bottom of the distributer, so that the ends of the pipes project above the bottom of the distributer-chamber to slightly different heights, the object of this arrangement being to insure the distribution of the oil through the pipes 28 in the proportions required by the different parts of the windmill-gearing. The quantity of oil discharged from the hollow valve-plug into the distributing-chamber at each movement `of the valve-plug being xed, the arrangement of the pipes 28 in the manner above specified will insure the passage of the greater portion of the oil through those pipes which have the shortest projections above the bottom of the distributing-chamber, and small quantities will pass out through the pipes which project above the bottom of the distributing-chamber to a greater height. The lubricator, as above described, will be supported in suitable'position by any convenient form of supporting means, which forms no part of this invention, and therefore needs no description or illustration.

The lubricator is especially designed, as already mentioned, for use in lubricating the working parts of awindmill-gearing; but it is to be understood that the lubricator may also be used to advantage upon any form -of machinery in which it is desirable to use a single oil-reservoir and a plurality of pipes fed by gravity to convey the oil from the reservoir l to the point where it is required.

In use the reservoir of the lubricator will be filled with oil, and the cavityin the valve-plug l0 will also be filled at the same time, because the weight on the lever 20 keeps the valve-plug normally in such position that the inlet-opening 12 registers with the oblong opening 8 in the upper part of the tapered valve-seat, so that oil may flow freely from the reservoir into the cavity in the interior of the valveplug 10. When it is desired to distribute oil from the reservoir to the bearings in the windmill-gearing or other machinery upon which the lubricator is employed, a pull upon the wire 23 will oscillate the lever 2O and turn the valve-plug sufficiently to bring the dischargeopening 13 over the bore on the lower branch pipe 9, so that the oil contained within the valve-plug may iow downward into the distributing-chamber and pass outward through the pipes 28 extending downward therefrom.

It will be readily understood from the foregoing description and the accompanying drawings that by varying the positions of the pipes 28 as regards the heights of their upper ends above the bottom of the distributing-chamber the quantity of oil passing through each of said pipes may be gradually adjusted to the requirements of each of the bearings and an economical distribution of the oil effected.

Having thus described the construction and operation of my invention, what I claim as new, and desire to secure by Letters Patent,
